SHUTTLE-CARRIER FORv SEWING-MACHINES.

SPECIFICATION forming part of -Letters Patent No. 234,112, datedNovember 9, 1880.

` Application filed February 18, 1880.

To all whom it may concern:

Be it known that we, PHINEAs E. AUSTIN and BYRON W. N IeHoLs, citizensofthe United States, residing at New Haven, in the county of New Havenand State of Connecticut, have invented certain new and usefulImprovements in Shuttle-Carriers for Sewing-Machines; and we do herebydecla-re the following to be a full, clear, and exact description of theinvention, such as Will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification. y

In thisinvention a hoodshaped carrier, which is adapted to inclose theshuttle and which can` be slid back and forth on the shuttie-lever, isattached thereto by a sleeve and is held to its place by a spiralspring. The shuttlecarrier is made so as to cover the swell of theshuttle sufficiently to keep it in position while in motion, and thisconstruction enables the shuttle to be poised or balanced so that itwillV not rest its own weight against the shuttle-race. It also preventsthe flying out of the shuttle if the race-covers be removed while themachine is in motion.

Referring to the accompanying drawings, Figure l is a bottom or underside view of the 'invention attached to the bed-'plate of asewing-machine of that class which is provided with a curvedshuttle-race. Fig. 2 is a top View of the shuttledriving lever with theimprovement attached. Fig. 3 is a longitudinal section of the same. Fig. 4 represents a modiication of the invention in which theshuttlecarrier is attached to the vibrating lever by a pin or screwpassing through a slot in said lever, and the spring is coiled on a rodone end of which is attached to the screw or bolt andthe other slides ina stud, as shown.

The shuttle-carrier A is attached to the vibratory'shuttle-lever by asleeve, B, and held in position by a spiral spring, C, which is coiledaround the shuttle-lever and presses against the sleeve ofthe carrier,forcing it outward and keeping it in position against the shuttle-race.

.The carrier is hood-shaped, as shown, and is constructed of metal orany other suitable material, and covers the swell or circle of theshuttle sufficiently to render it impossible to remove or insert theshuttle without moving the carrier away from tue shuttle-race. The topside of the carrier may be cut away, as shown by dotted lines, to allowthe passage of the thread around the tension-spring on the shuttle incases where such a spring' is used.

The shuttle-lever is in two parts, D D', which are clamped together by aclamp-bolt, E, as shown, so that said lever can be adjusted as to lengthto take up wear and regulate the tension of the spring.

The carrier is prevented from turning by a pin, d, projecting through aslot, b, in the sleeve.

In order to remove the shuttle from the carrier it is slid back on thelever, and to insert it in position for use it is only necessary toenter the point of it between the carrier and the side of the race andit is readily pressed into place, the spring allowing the carrier torecede sufficiently for the purpose and then automatically forcing it toits place.

The modilication shownin Fig. 4 is adapted for machines as they are nowgenerally made. The carrier is attached to the lever by a screw, F,which passes through a longitudinal slot, Cr, in the lever D, and thespring C is coiled around a rod, one end ot' which is secured to thescrew F and the other slides in a stud or projection, H, on the lever.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

l. The combination of the hood-shaped shuttle-carrier A, provided withsleeve B, the spring C, and adjustable shuttledever D D', allconstructed and arranged as herein set lforth, for the purposespecified.

2. The combination of the sh Little-carrier A, having sleeve B, providedwith slot b, spring C, adjustable lever D D', clamp pin or bolt E, andpin d, all arranged asherein set forth, for the purpose specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
